摘要
应用气相色谱研究了糖蜜酒精废水两相UASB处理工艺各段中有机物的去除情况 ,结果表明 :酸化反应器内 ,易降解有机物的去除率基本上为 1 0 0 % ;产甲烷段反应器内 ,因易降解化合物在酸化反应器内大部分被去除 ,剩下的化合物在该段反应器内去除率偏小 ,仅为 80 %。质谱结果证实 ,进水中的酚类化合物经两级处理后 ,被有效去除。
Removal of organic compounds of molasses wastewater in two phase UASB process was studied by gas chromatography. The results showed that the removal rates in acidifying UASB were nearly 100%, while those in methanogenic UASB were only 80% because of hard degradation of the residual compounds. According to the removal rates of organic compounds, the process of minor aeration and coagulation should be cancelled. The results of mass chromatography showed that phenolic compounds of influents were completely removed after two-phase UASB treatment.
